Abstract
A process for preparing an ammonium or phosphonium borate salt KA containing a cation K and an anion A. The process includes providing a melt of a borate salt K1A, and adding a solution of an ammonium or phosphonium salt KA1 in a solvent or solvent mixture (i), wherein K is an organic ammonium or phosphonium cation, and A is a borate anion of formula (Ia) or (Ib).
Claims15
A process for preparing an ammonium or phosphonium borate salt KA containing a cation K and an anion A, comprising the steps:
- (a) providing a melt of a borate salt K1A;
- and
- (b) adding a solution of an ammonium or phosphonium salt KA1 in a solvent or solvent mixture (i),
- wherein
- K is an organic ammonium or phosphonium cation;
- A is a borate anion of formula (Ia) or (Ib)
- wherein Hal is halogen, and
- is a bidentate radical derived from a 1,2-, 1,3- or 1,4-diol, from a 1,2-, 1,3- or 1,4-dicarboxylic acid or from a 1,2-, 1,3- or 1,4-hydroxycarboxylic acid by abstracting the two H atoms of pairs of adjacent OH groups of the respective diol, hydroxycarboxylic acid or dicarboxylic acid in 1,2-, 1,3- or 1,4-position;
- A1 is an organic or inorganic anion;
- and
- K1 is an ammonium cation different from K.
